Filter by:Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous disease that affects only a fraction of those who smoke tobacco. The origin of this variability in susceptibility to develop COPD is unclear, but understanding its underlying biology has important implications for our ability to design suitable preventative and therapeutic strategies for its management. This Department of Defense (DOD) discovery research proposes to develop methodologies and generate preliminary data needed to lay the foundation for a large study that would investigate the underlying biological susceptibility of those who smoke tobacco to develop COPD.
- Objective: Our study aims to evaluate the effectiveness of the "STOP" (Sevrage Tabagique à l'aide d'Outils dédiés selon la Préférence: Smoking Cessation using preference-based tools) intervention, a preference-based smoking cessation intervention for smokers with low socio-economic position (SEP). - Methods : STOP is a randomised, multi-centre, single blinded, intent-to-treat trial. Participating centres include primary care practices (community, municipal or general health clinics), hospital-based facilities, and healthcare institutions specialised in addiction treatment. Smokers with low SEP will be randomised into either the intervention or control group. Persons randomised to the control group will be accompanied by their health professional according to standard practice. Participants randomised to the intervention group will receive the same smoking cessation advice, drug (varenicline, champix,..) prescription and support as participants in the control group, but they will also have a choice of being given free Nicotine Replacement Therapy (NRT) (transdermal patch, gum, spray, inhaler, sublingual tablets/lozenges) and/or an electronic cigarette + e-liquid on the spot to aid their quit attempt. Follow-up appointments will take place at around 7 to 14 days, 1 month, 3 months and 6 months after inclusion, according to the participant and health professional availability. The main outcome measure of this study will be the 7-day point prevalence tobacco abstinence at 6 months after inclusion (yes/no), defined as self-reported abstinence for at least 7 days, This self-reported abstinence will be validated by measured exhaled carbon monoxide, unless this measurement is unavailable due to the ongoing covid-19 pandemic.
The survey participants are divided into a smoking and non-smoking group. The smoker group is further divided according to the quantity and quality of nicotine ("normal" smoking, vaping). After reaching a steady state, the cutaneous blood flow at rest in the extremities of all participants is determined by Laser Doppler Imaging as a reference value. Laser Doppler Imaging produces images of the blood flow using perfusion units (PU). Subsequently, the perfusion is measured again after smoking/vaping. The difference in skin perfusion of the extremities is calculated (δ-Perfusion). All measurements are performed under controlled vital parameters (body temperature, systolic and diastolic blood pressure, heart rate) and controlled room temperature as well as 15-minute acclimatization of the patients.
The main purpose of this research study is to compare traditional behavioral smoking cessation therapy with a different type of behavioral therapy-known as behavioral activation problem solving (BAPS)-for smoking cessation. Standard smoking cessation counseling (SC) focuses on self-monitoring, identifying smoking triggers and how to manage them, relaxation and social support for non-smoking, and relapse prevention. BAPS focuses on recognizing he feelings you are having that lead to smoking and how to overcome those feelings and focus on activities that discourage you from smoking and avoid activities that encourage you to smoke. Both counseling types include gathering information about your personal smoking patterns, your likes, dislikes, and other personal characteristics about your lifestyle. Half of participants who enroll in the study will receive standard smoking cessation counseling (SC) and half will receive BAPS counseling. We will compare the rates of quitting smoking across the two groups at the end of treatment (study week 10), and 12 weeks after the end of treatment (study week 26)
This is a research study to find out if a smoking cessation medications, either varenicline or nicotine replacement products (patches or lozenges), are effective when given to smokers, remotely, as a one-time sample. Participants will either receive a sample of varenicline, nicotine patches and lozenges, or neither. This will be decided randomly. Participants have a 50%chance of receiving varenicline, a 25% chance of receiving nicotine products, and a 25% chance of receiving neither. If the participant is assigned to a group that receives free samples, they will be mailed to them free of charge. There is no requirement to use them, and it is completely up to the participants. There is also no requirement to quit in this study. The study lasts for six months, and will involve six total surveys. In addition, investigators ask that participants complete daily diaries (about 1 minute each) for the first 4 weeks of the study. Both varenicline and nicotine replacement products are well-established medications that help smokers quit.
This project will compare the effectiveness of an HIV-specific comprehensive wellness intervention designed to have broad appeal to smokers living with HIV to the effectiveness of standard care services that include referral to the National VA Quitline and SmokefreeVET texting program. Participants in both arms will have access to pharmacotherapy available through their Veterans Affairs (VA) healthcare providers.
Smokers with schizophrenia spectrum disorders have high rates of morbidity and mortality from smoking-related diseases compared with the general population and current options for smoking cessation in this vulnerable group are unsatisfactory. Considering that most people with schizophrenia spectrum disorders continue smoking, it is urgent to consider alternative and more efficient interventions to reduce or prevent their morbidity and mortality. Switching to combustion-free technologies for nicotine delivery (I.e. e-cigarettes) could be a pragmatic and much less harmful alternative to tobacco smoking with the possibility of significant health gains. Emerging research is suggesting that ECs may be useful for smoking cessation and relapse prevention in people with schizophrenia spectrum disorders. In particular, a study conducted with JUUL e-cigarette with 5% nicotine strength showed that this product had sufficient nicotine delivery and product appeal to determine high success rates in heavy smokers with schizophrenia spectrum disorders. In consideration of these preliminary findings, we hypothesized that switching smokers with a schizophrenia spectrum disorder diagnosis to JUUL e-cigarette with 5% nicotine strength could result in higher success rates compared to JUUL e-cigarette with 1.7% nicotine strength. Recent work indicates that nicotine PK of the JUUL e-cigarette with 5% nicotine strength (a device that utilizes a nicotine salt formulation) approximates the nicotine delivery of combustible cigarettes and that the 5% nicotine strength product is far more efficient in delivering nicotine compared to the sister product with 1.7% nicotine strength. Both products are identical in their appearance, making them suitable for a double-blind study design.
The purpose of this voluntary research study is to learn about the potential effects that black raspberry (BRB) lozenges may have on reducing the damage caused from cigarette smoke in mouth cells in adult smokers, which may be useful in reducing health risks associated with smoking.
Although rates of cigarette use are declining, the proportion of nondaily smokers is rising, particularly among young adults. Among young adults, nondaily smoking is associated with negative health consequences and, for some, may lead to the establishment of life-long smoking patterns. The goal of this project is to understand the behavioral, psychological and neurobiological factors that contribute to cigarette use in nondaily smokers to aid the development of tailored evidence-based interventions.
The purpose of the study is to learn more about the relationships between the brain, behavior, and natural daily exposure to particular environments, including the places where smokers regularly spend time and specific retail outlets.
